Our lab is using Mass Hunter Qual (B.05.00) for QTOF data analysis (Agilent iFunnel 6550 QTOF) and we usually export mass or UV chromatograms as csv format by clicking right mouse button on a spectrum of interest, so that such raw data can further be processed using other programs. The problem is that current exported data points have significantly diminished from very recently, when compared to those exported previously. I just don't know how to adjust a number of exported data points. Is there anyone who has experienced a similar issue or is willing to shed light on that?

You say that the exported data points of recent results have 'significantly diminished' recently - do you mean that the number of spectral peaks have dropped? Or that their area has dropped? How do the results look like in Qual proper?

Hi Hexatriene, sorry for the confusion! What I meant is that the exported data point numbers have dropped. In fact, my colleague figured that out-it is just a matter of how data are extracted in "extraction format" function. It was accidentally chosen as "centroid" when the export was conducted, which led to a substantially diminished number of data points exported.
